Be it known that l, TiioMAs A. JnNiiiNs,A

al citizen ofthe United Sta-tes, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certainy new and useful Improvements in Surfacing Containers for Tracing Cloth, of which the following is a specification.

This invention relates to improvements in surfacing devices for tracing cloth and more particularly toa novel and improved powder dispensing container for use by draftsmen for preparing the receiveA ink;l

The primary object of the invention is to y provide a receptacle or container for uniformly dispensing a specially prepared powder by sifting the same on a tracing cloth and then treating the surface of the cloth by applying the powder to the same to remove any excess grease or moisture adhering thereto whereby the cloth will more readily take the ink.

lt has been the practice when sprinkling or otherwise arbitrarily sifting and applying a powder, such as prepared chalk and the like to smooth the surface of tracing cloth and to clean it of grease and moisture adhering thereto, by rubbing the powder over the surface of the cloth with the hand or with a rag or the like, and then removing the excess powder after the cloth has been treated but the objection to this practice resides in the fact that the powder is not evenly or uniformly distributed over the entire surface, thus leaving parts of the glazed cloth unprepared which do not readily take the ink. ln addition there is great waste of the powder used without full and complete results, and the excess powder has a tendency to adhere to the clothing of the user by being blown or dusted from the cloth being treated. i

l. One of the objects of the invention therefore is to produce a novel and improved holder or receptacle. wherein the bodyk is formed of two telescopic frictionally engaged members, one of said members havingv a meshed vfabric disposed over a false bottom permitting the powder to be sifted, andthe other member is provided with a fibrous inaterial, such as felt or the like for applying the sifted powder evenly over the surface of the cloth for treatment.

Another and very important object of the invention is the provision of a sifting con surface of tracing cloth to taincr particularly adapted for Luse by vdraftsmen for preparing tracing cloth, and

one in which the parts are'extremely simple in construction, vasily assembled, rigid and durable, highly eiiicient in operation, practical and capable being manufacturedat- 'a very low cost whereby its commercial possibilities ai'e greatly enhanced.v

The invention willr be best understood from a consideration of ther following detailed description taken in accordance with the accompanying drawing forming a part of this'specifieation, with the understanding however, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified as long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

lf attain these objects and others in the accompanying' drawings, wherein Figure l is an elevation showing the top of the reservoir or container.

Figure 2 is an elevation showing` the bottom thereof.

Figure 3 is a longitudinal sectional view taken therethrough.

Referring now to the drawings wherein like parts designate corresponding parts throughout the several views, Figure l designates a substantially rectangular receptacle or container the top of which is provided with a felt pad 2 or the like of any fibrous material. to be used .for applying thc sifted powder over the tracing cloth. The rectangular member l is adapted to frictionally receive an inner, telescopic member 5 provided with a false bottom 4 and attached to the respective ends of the inner section and stretched across and over the false bottoni l have provided a ineshed piece of fabric or screening material' 2? through which the powder may be sifted onto the A cushion designated GOv reverserh bottom side up, and the inner seotion 5 slid into the body portion of the outer section. In actual use, to those skilled in the art it will be apparent that by simply shaking powder over the tracing cloth, the proper quantity of powder will fall through the fal'iric, and then reversing the receptacle the said powder may be .more evenly spread and rubbed into the cloth'by the feit pad 2 so that the powder will absorb any moisture and clean the cloth ofgrease or any foreign matter adhering thereto. y

.In the accompanying drawings, I have form by way of example, and which in practice has been found to be highly satisfactory in obtaining the desired results. It willr be obvious however that othervembodiments may be adopted, and that various .changes in the details of construction maybe resorted to by those skilled in the art without f,

departing from .the spirit and scope ofthe invention. It is ,furthermore kunderstood that the invention is not necessarily limited or restricted `to the precise elements shown except in so far as such limitations are specified in the subject mattei' being` claimed.

Having shown an'ddescribed my invention what I now claim as new and desire to secure by'Letters 'Patent of the United iStates, is.:-

A receptacle ofthe class described comprising two interfittingrsubstantially rectangular members having la false bottom, a

cushion secured tol thefinner member adjacent the edges ofthe false bottom, a screen- .illustrated my invention embodying 1n one ingrfa-brici covering the outer ends of the innerniember and disposed over the cushion and said false bottom andra felt pad or rubbingsurface on the top of the `outer section for applying sifted powder to a tracing cloth.
